”Over the new year 2009-2010, an international group of 1500 men and women from 42 nations went to Egypt to join a Freedom March to Gaza. They did this to protest the current blockade of Gaza.

To protest the fact that a year after the terror attack by Israeli armed forces destroyed most of their homes, hospitals, schools, and other public buildings, they have no possibility to rebuild because their borders are closed.
